Android手机卫士之设置密码对话框

本文实现初次设置密码验证过程，首先实现如下效果

布局如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical">
 <TextView
 style="@style/TitleStyle"
 android:background="#f00"
 android:text="设置密码"
 />
 <EditText
 android:id="@+id/et_set_psd"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:hint="设置密码"
 />
 <EditText
 android:id="@+id/et_confirm_psd"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:hint="确认密码"
 />
 <LinearLayout
 android:layout_width="match_parent"
 android:layout_height="wrap_content">
 <Button
  android:id="@+id/bt_submit"
  android:layout_width="0dp"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  android:text="确认" />
 <Button
  android:id="@+id/bt_cancel"
  android:layout_width="0dp"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  android:text="取消" />
 </LinearLayout>
</LinearLayout>

其中TitleStyle的代码如下：

<resources>
 <!--
 Base application theme, dependent on API level. This theme is replaced
 by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
 -->
 <style name="AppBaseTheme" parent="android:Theme.Light">
 <!--
  Theme customizations available in newer API levels can go in
  res/values-vXX/styles.xml, while customizations related to
  backward-compatibility can go here.
 -->
 </style>
 <!-- Application theme. -->
 <style name="AppTheme" parent="AppBaseTheme">
 <!-- 在去头的同时还保持高版本的样式主题 -->
 <!-- All customizations that are NOT specific to a particular API-level can go here. -->
 <item name="android:windowNoTitle">true</item>
 </style>
 <style name="TitleStyle">
 <item name="android:gravity">center</item>
 <item name="android:textSize">20sp</item>
 <item name="android:textColor">#000</item>
 <item name="android:padding">10dp</item>
 <item name="android:background">#0f0</item>
 <item name="android:layout_width">match_parent</item>
 <item name="android:layout_height">wrap_content</item>
 </style>
</resources>
